This boring looking electrical box located on the streets of Lisbon has been transformed by Illustrator and street artist Diogo Machado. The talented artist gave the electrical box a white cracked outer shell with a ceramic style pattern hidden underneath. It all works thanks to the clever use of shading that makes the white outer shell appear to pop from the rest of the structure.
The end results is an amazing looking optical illusion. See more of the artists work via his website.
